Electro-Optical Characteristics (TA=0°C to 70°C, TA=25°C-Typical, unless otherwise specified)
Switching Specifications (TA=25°C)
Notes
1. DC current transfer ratio is defined as the ratio of output collector current, IO, to the forward LED input current, IF times 100%.
2. Pin 7 open.
3. Device considered a two-terminal device: pins 1, 2, 3 and 4 shorted together and pins 5, 6, 7 and 8 shorted together.
4. Using a resistor between pin 5 and 7 will decrease gain and delay time.
5. Common mode transient immunity in logic high level is the maximum tolerable (positive) dVcm/dt on the leading edge of the common mode pulse,
VCM, to assure that the output will remain in a logic high state (i.e. VO>2.0 V) common mode transient immunity in logic low level is the maximum
tolerable (negative) dVcm/dt on the trailing edge of the common mode pulse signal, VCM, to assure that the output will remain in a logic low state
(i.e. VO<0.8 V).
6. In applications where dv/dt may exceed 50,000 V/
µs (such as state discharge) a series resistor, R
CC should be included to protect IC from destruc
tively high surge currents. The recommended value is RCC
IV
